Finite element simulation of ballistic impact on single jersey knit fabric
Composite Structures, 2017Abstract Knitted fabrics are constructed from interlocking loops of yarn. Curvature in the yarn provides stretchability, making them well suited for garments that will cover areas of the body that require large relative motion. Although most current soft armors are composed of woven textiles, knitted fabrics made of aramid fibers such as Kevlar may ...

Response Simulation of a Micro Reinforced Concrete Target Under Ballistic Impact
International Journal for Computational Methods in Engineering Science and Mechanics, 2014The response of concrete structures subjected to impact loading has received extensive attention in both civil and military applications. Research on improving the shock resistance of concrete has led to the development of cementitious composites. Micro Reinforced Concrete (MRC), a type of cementitious composite, is a concrete matrix embedded with ...

Thick AA7020-T651 plates under ballistic impact of fragment-simulating projectiles
International Journal of Impact Engineering, 2015Abstract The ballistic performance of an Al alloy AA7020-T651 (AlZn4.5Mg1, 3.4335) against fragment-simulating projectiles (FSPs) is investigated at impact velocities between 900 m/s and 1500 m/s. The target plates are considered as thick regarding the ratio between the specimen thickness (40 mm) and the projectile diameter (20 mm).

A Simple Analytical Model to Simulate Oblique Ballistic Impact onto Fabric
Applied Mechanics and Materials, 2011A simple analytical model for oblique ballistic impact of projectiles into fabrics are presented. This model is extension of Chocron-Benloulo penetration model. Results are compared with experimental data. There is good agreement between analytical and experimental results.

Ballistic impact simulation for the safety in tool machines
2012Numerical control (CNC) boring and routing machines use curtains made from resistant, but flexible materials to protect end-users from the projection of tool pieces. These curtains allow the work piece to gently pass through, but have to firmly stop every small sharp piece or fragment ejected by fast drilling tools at the highest speed.
